A Biblical judge (Hebrew: שופט šōp̄êṭ/shofet, pl. שופטים šōp̄əṭîm/shoftim) was "a ruler or a military leader as well as someone who presided over legal hearings." These judges appear most often in the Book of Judges, which is named after them.
Kenneth Kitchen argues that following the conquest of Canaan by Joshua until the formation of the first Kingdom of Israel and Judah (ca. 1150–1025 BC), the Israelite tribes formed a loose confederation. No central government existed in this confederation; in times of crisis, the people were led by ad hoc chieftains, known as judges (shoftim).
However, "almost all" scholars have abandoned the idea that Joshua carried out a conquest of Canaan similar to that described in the Book of Joshua. Likewise, there is considerable doubt among scholars that a period resembling the one described in the Book of Judges ever existed in ancient Israel.
Moses was a shofet over the Israelites and appointed others to whom cases were delegated in accordance with the advice of Jethro, his Midianite father-in-law. The Book of Judges mentions twelve leaders who judged Israel: Othniel, Ehud, Shamgar, Deborah, Gideon, Tola, Jair, Jephthah, Ibzan, Elon, Abdon, and Samson. The First Book of Samuel mentions Eli and Samuel, as well as Joel and Abiah (two sons of Samuel). The First Book of Chronicles mentions Kenaniah and his sons. The Second Book of Chronicles mentions Amariah and Zebadiah (son of Ishmael).
